ComforPedic® iQ™ 180 is a luxury firm mattress from iQ collection introduced by Simmons in January 2014. The iQ collection combines three brand new technologies in this "self adjusting" memory foam mattress. These are Micro Diamond™ Infused AirCool® Memory Foam (This exclusive foam leverages its diamond particles' conductive properties to effectively move heat away from the body), the spun rayon jersey knit cover and Smart Response™ foam chambers - a self-calibrating technology that naturally responds and continuously adapts to the body – without motors, buttons, plugs or electronics.

Smart Response™ is a system uses foam chambers to adjust the balance of support in response to the weight and contours of the body. Simmons claims that it "automatically calibrates to your body’s weight and position on the mattress." These are polyurethane chambers filled with very porous foam. Intake and outflow one-way air valves (check valves) allow the chambers to release air when more pressure is applied or increased, and let it in when pressure is reduced. With only one outflow check valve and two intake, the chambers reinflate more quickly than they deflate. The number and arrangement of chambers (per side) is set, the chamber size depends on the size of the mattress. The arrangement is engineered for optimal support to the torso.
